This area chart shows annual car sales trends from 2013 to 2023, with a green filled region beneath a black line to emphasize the overall sales trajectory. The visualization uses D3 v5 to load a CSV dataset from GitHub, parse the dates, and render the chart with a time-scaled x-axis and linear y-axis. It applies `d3.line` and `d3.area` generators with a basis curve, while axes are drawn using `d3.axisBottom` and `d3.axisLeft`. Grid lines are created via tick sizes, and axis labels are manually added with rotation for clarity.
